The finding of larvae on Crataegus, Malus and Amelanchier in North America apparently having the same DNA barcode as European S. oxyacanthella (BOLD:AAF3421) led EvN to re-examine specimens identified as S. pomivorella (Packard, 1870) in CNC and USNM. All show genitalia inseparable from S. oxyacanthella, and we thus synonymise Stigmella pomivorella. This leafminer apparently was already introduced in the USA during the 19th century. Details will be published elsewhere. (Van Nieukerken et al. 2016)
